[Indications for lymph node dissection in hepatocellular carcinoma].

Objective: To determine the indications for lymph node dissection in patients with hepatocellular carcinoma.

Material And Methods: The study included 105 patients with hepatocellular carcinoma who underwent dissection of 8, 9, 12, 13 and 16a2 groups of lymph nodes. Concomitant liver diseases were not a contraindication for lymph node dissection.

[Salvage liver transplantation for hepatocellular carcinoma].

Objective: To analyze clinical course and the results of salvage liver transplantation in patients with recurrent hepatocellular carcinoma (HCC) after liver resection.

Material And Methods: A 54-year-old man with HCV-infection and HCC and 22-year-old woman with fibrolamellar variant of HCC underwent resection of the right and left liver lobe, respectively. The first patient experienced recurrent HCC four times with an interval of 3-6 months within 2 years after surgery.

[Results of the repeated hepatic surgery on the reason of malignant tumors].

The work is based on an analysis of 95 clinical observations of patients with primary and metastatic liver disease who were in the surgical department of tumors of the liver and pancreas of the State Research Institute named by N.N. Blokhin of RAMS from 1990 to 2011.

[The possibilities of surgical treatment of hepatocellular cancer in patients with liver cirrhosis].

154 radical liver resections were performed on the reason of the hepatocellular cancer, of them 33% in patients with liver cirrhosis. Liver function was assessed using the Child--Pugh score. Liver cirrhosis and extensive liver resections proved to be the independent complication and lethality risk factors.

[Surgical treatment of hepatocellular carcinoma].

Experience of surgical treatment of 171 patients, suffering hepatocellular carcinoma (HCC), was summarized. Extensive hepatic operations were performed in 99 (71.2%) patients, of them in 22.

Deregulation of hepatocyte nuclear factor 4 (HNF4)as a marker of epithelial tumors progression.

Tissue-specific transcription factors forming the regulatory cascades which determine the specification and differentiation of epithelial cells during embryogenesis, play the central role in the control of functional and morphological properties of different cell types. Hepatocyte nuclear factors (HNFs) network is one of the most investigated tissue-specific regulatory systems which controls the specification and maintenance of differentiation of several epithelial cell types. Nuclear receptor HNF4α is one of the central elements of this regulatory network in the liver.

[Surgical and combined treatment of patients with metastatic liver and lymph nodes invasion by colorectal cancer].

527 patients were operated on for liver colorectal cancer metastases. Of all cases of lymphadenectomy during liver resections, lymph nodes invasion was morphologically proved in 43 patients. 3- and 5-year survival rate in this group was 12,8+/-6.

[Multivisceral resections at disseminated abdominal tumors].

Overall 131 multivisceral resections at disseminated abdominal malignant tumors have been performed. The main arguments to extended operations were local dissemination of tumor (35.1%), synchronous hepatic metastases (49.

[Synchronous operations in metastatic cancer of the liver].

The resection of the liver has been performed in 661 patients including 154 (23.3%) cases of synchronous metastatic cancer of the liver. Among the latter patients primary tumor was removed in one stage with liver resection in 56% cases.
